Question

If VBE is zero, state the effect on power BJT.​

Answer 1

hi buddy

what is the full form of VBE and BJT

Answer 2

Answer:

Below is NPN BJT transistor Vbe Ic characteristics and approximate this equation as:

Ic = Is*{e^(Vbe/Ut)-1}

and following this they say when Vbe=0, Ic becomes equal to Is.

But in real the equation is:

Ic = Is*(e^(Vbe/Ut) - 1)

And in this case when Vbe is set to zero Ic becomes zero.
